Plotting many, many points on a map.

What free website(s)/program(s) can I use to plot a large database of addresses on a map? Multiplottr.com allows me to load in my data and then export a .kml file, which I can import into Google Maps. But it only works for a subset of data; it cannot handle my full database of 15,000 locations.
I like multiplotter because beyond just street address and city/state/zip, I can attach a specific color pin and a label to each datapoint. Looking for something that produces a similar result (preferably in cooperation with Google Maps) and can handle a much larger data set. I'm starting out with an excel file.

Maybe a bit much for your needs, but Django + GeoDjango would work.

You can set up google maps to use a datasource for the positions on a map, which can be a Google Docs spreadsheet. So if you can export your data into a format that matches the format of the datasheet, you can save it as an Excel or CSV file, open it in Google Docs, and then process that with Google Maps. Not sure if that would be easier or harder than BatchGeoCode (never used it).
Of course, I'm not sure what the data size limit is for this...it's possible this is the same limitation you experienced with Multiplottr.

Might be interested in the Million Marker Map by Maciej Ceglowski and Jason Williams.
